OIL-BURNER.

SPECIFICATION forming part Of Letters Patent No. 736,664, dated August 18, 1903. 7 Application filed May 26, 1903. Serial No. 168,797. (No modeh) ing to be a full, clear, and exact description of the same.

My invention relates to an apparatus for :w the preparation and combustion of hydrocarbon oils.

It consists in the combination of a shell with oil and steam supply nozzles, an anterior mixing-chamber, a second large chamber with a contracted "connection between the two, a Qfinal chamber and a nozzle-discharge therea into, and a second steam-inlet passage acting upon and with the products received at this delivered to the burner.

point and previous to their delivery to the burner opening or discharge.

. It also comprises details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is an exterior elevation. Fig. 2 is a longitudinal section through the axis.

It is the object of my invention to provide for a series of nozzles, chambers, and connected passages substantially in line and so disposed with relation to oil and steam inlets that the oil when first admitted is subjected to the action of the hot steam and is also mixed therewith in a chamber prepared for the purpose. It is then conducted through a contracted passage and expanded into another mixing-chamber, from which it is delivered through a second contracted passage or nozzle, and is there mixed with a further supply of steam, which serves to further heat and pulverize the oil product before being At the end of this chamber a baffle-plate is disposed so that the mixture from the last chamber will impinge upon this plate and be prevented from passing in a direct line to the burner or discharge opening.

As shown in the drawings, 2 is an outer shell, which is here shown as being substantially pearshaped having the larger diameter toward the inlet end of the apparatus. Into this inlet end, which is screw-threaded or otherwise provided with a coupling device, is fitted the nozzle A, having a convergent opening 5, through which and the subsequent narrow passage the oil is admitted substantially. axially or in center line of the shell '2. The opposite end of this shell has fitted into it a mixing-chamber 4:, which opens in a bellshaped form toward the oil-admission nozzle, which nozzle is here shown as extending slightly into the bell-shaped chamber A. This chamber forms a continuation of the threaded sleeve or collar 4, which is screwed into the outer end of the shell 2, so that the bell 4: projects into the shell and has its open mouth located within the larger diameter of the shell.

3 is a steam-passage opening transversely into the side of the shell 2 and in such relative position with the oil-admission nozzle and the bell. 4 that the steam thus admitted will enter the bell and mingle with the oil therein and will also [ill the space within the shell 2, surrounding the bell, this space extending nearly to the front end of the bell. The steam entering this annular or surrounding chamber serves to heat the oil which is discharged into the bell 4: and to maintain the oil and steam which are mixed therein at a sufficiently high temperature to commence the proper mixing of the two. In addition to this the size of the shell 2 causes itto act as a sort of reservoir of elastic medium, which prevents a pulsating or puifing movement of the vapors which are passed through th'e apparatus to the burner. The size and shape of the bell 4c are such that the jet of oil and the steamenter with a swirling movement, which movement also takes place in the surrounding chamber of the shell 2. From the bell 4 a contracted passage 6 passes toward the forward portion of the part 4, and at the front it is expanded into a divergent chamber 7, so that the oil and steam first mixed and heated in the bell 4 are driven together through the passage 6 and allowed to again expand in the chamber 7.

9 is a chamber convergent toward the front and having its base and larger portion opening into the chamber 7 This chamber 9 is screwthreaded on the outside and is fitted into corresponding threads within the part 4:, a flange or collar 8 serving for the application of a wrench by which to turn it in or out. On the exterior of this part 9 is fitted a T 10, having a transverse inlet-passage 15 opening into the side. The interior diameter of this T is greater than the convergent chamber or nozzle 9, so that the steam admitted thereinto fills the chamber in line with the steam-inlet and surrounds the chamber 9, so that the steam and oil, having expanded into the chamber 7 and the first portion of the chamber 9, are again converged through the forward portion of this chamber 9 and subjected to the additional heat of the steam entering through 15.

To the front of the T 10 is connected a cylindrical or other chamber 11, and into this chamber, which is of considerable length, the contracted front end of the chamber or nozzle 9 discharges.

shown at 16,'the remainder of the apparatus being outside the furnace-front and within easy reach.

The discharge-nozzle may be of any wellknown or suitable form not material to the present application.

In the side and near the front of the chamberll is an opening having a screw-plug 12 threaded therein. This screw-plug carries a baffle-plate 13, which when the plug is in place stands directly in the line of discharge of the chamber 9.

The steam which is admitted through the passage 15 and which surrounds the chamber '9 also passes forward aroundthis chamber into the chamber 11, so that the oil and steam which pass out through the contracted front of 9 are again allowed to expand within the chamber 1] and by reason of the baflie-plate 13, against which they impinge, they are checked, and a final mixing and heating takes place within the chamber 11, after which the surplus, passing around the baffle-plate 13, will escape to the burner under such pressure as may be maintained within the apparatus It will be seen by this construction that the long threaded joints by which the parts are united will maintain themselves without leakage, and these joints enable the apparatus to be easily taken apart for inspection or repairs.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination in an oil-burner of an exterior pear-shaped shell convergent from the rear to the front, a bell-shaped chamber within the shell having its open mouth presented toward the rear thereof and a contracteddischarge-passage toward the front, an oil-admission nozzle-opening into the rear of the bell, a steam-inlet opening transversely across the mouth of the bell and the oil-nozzle whereby steam is admitted into the interior of the bell to mix with the oil and also exterior thereto to surround and heat the bell.

2. The combination in an oil-burner of an exterior pear-shaped shell convergent from the rear toward the front, a screw-threaded oil-admission nozzle fitted axially into the rear of the shell, a screw-threaded sleeve or collar' fitting the front end of the shell having an extension inwardly toward the rear, said exten sion being enlarged to form a bell into the open mouth of which-the oil-inlet discharges,a contracted passage leading forwardly from the bell and a divergent expanded chamber within the sleeve, into which the passage opens, a steam-passage opening transversely into the shell whereby steam is mixed directly with the oil in the bell and also surrounds the bell, a second mixing-chamber axially in line and in front of the sleeve or collar, and a second steam-inlet contiguous thereto.
